Functions (Need) Exercises

Exercise 1 (Do you know why?) ☻

The following code works as expected despite not having an else statement. Please use a Markdown cell to explain why?

def greeting(name):
    if name == 'Batman':
        return 'Hello Batman! So, nice to meet you!'
    return f'Hello {name}!'

Exercise 2 (Chubby or not) ☻

Write a Python function named calculate_bmi.

  • The function should take two parameters:
    weight (in kilograms) and height (in meters).
  • The function should calculate the BMI (Body Mass Index) using the formula BMI = weight / (height ** 2).
  • Based on the calculated BMI, the function should return a string indicating the BMI category based on the following criteria:
Category BMI Range
Underweight BMI less than 18.5
Normal weight BMI between 18.5 and 24.9
Overweight BMI between 25 and 29.9
Obese BMI 30 or more

Exercise 3 (Factorials) Write a function that accepts an integer n and returns its factorial. Ensure that your function gracefully handles negative numbers.
